## Description

Max Tool is an advanced toolkit for the MAX web client (<a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/2073e30f17bbdb83d512764bd03767bcc75c4e1020c93e0094132b369fdc5d02/http%3A//web.max.ru" rel="nofollow">web.max.ru</a>): session management, privacy and interface customization. Everything runs locally - tokens and session data are never sent anywhere and are used only inside your browser.

Features:

• Accounts - save multiple sessions with name and avatar, switch between them in one click. Manual login by token.

• Token export - copy the current session token in one click.

• Privacy - "Hide read" (don't send read receipts), "Hidden online" (don't appear online), hide the typing indicator, block analytics, hide ads, mute the third-party AppTracer tracer, plus your own opcode-based blocks.

• Anti-delete - messages deleted by the other person stay visible for you (a removed message is slightly dimmed).

• WebSocket inspector - see which opcodes are sent to and received from the server; add any outgoing opcode to your blocks with one button. For a detailed breakdown there's a dedicated "MAX" tab in DevTools (F12): the full decoded JSON of every request, filters, flags for frames modified by the extension, and a view of the original.

• Device spoofing - change the device name, OS, User-Agent, screen size, timezone and Device ID sent on connect. Ready-made presets included.

• Appearance - set an accent color, app background, AMOLED black theme, your message color, font, text size and corner roundness, or write custom CSS. Changes apply instantly. Built-in color picker.

• Interface - Russian and English, theme selection (auto/light/dark).

The extension works only on <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/2073e30f17bbdb83d512764bd03767bcc75c4e1020c93e0094132b369fdc5d02/http%3A//web.max.ru" rel="nofollow">web.max.ru</a> and collects no data.
